How Does Liquid Silicone Rubber Molding Work?
January 26, 2024

Liquid silicone rubber (LSR) molding is a highly versatile and effective manufacturing process used to produce a wide range of silicone rubber parts and components. The process involves injecting molding silicone rubber into a mold cavity, where it is then cured and solidified to form the desired shape.

The slilicone injection molding service process begins with the preparation of the liquid silicone rubber material, which typically consists of a two-part silicone elastomer system. The two parts, a base material and a catalyst, are mixed together in precise proportions to initiate the curing process.

Next, the liquid silicone rubber is injected into the mold cavity using a specialized injection molding machine. The mold itself is typically made of high-quality steel and is designed to impart the desired shape and features to the final product.

Once the mold is filled with the liquid silicone rubber, it is closed and subjected to heat and pressure to facilitate the curing process. The heat activates the catalyst in the silicone rubber, causing it to crosslink and solidify. This curing process usually takes a few minutes, depending on the specific material and part requirements.

After the curing is complete, the mold is opened, and the solidified silicone rubber part is removed. The part may undergo additional post-curing processes, such as heat treatment or secondary operations like trimming or bonding, to achieve the desired final properties and quality.

LSR molding offers several advantages, including excellent dimensional accuracy, precision, and repeatability. It allows for the production of complex shapes, thin walls, and intricate details with minimal parting lines. The resulting parts exhibit outstanding temperature resistance, chemical resistance, and flexibility.

Overall, liquid silicone rubber molding is a highly efficient and effective manufacturing process used to produce a wide range of silicone rubber parts for various industries, including medical, automotive, electronics, and consumer goods. Its versatility and superior properties make it a preferred choice for many applications requiring high-quality silicone rubber components.
